    file request: QS motor, 205 V3 T5 for Sevcon gen4

    hi, A friend of us has all the goodies to program these sevcons, so i dont worry about that part. We want to use a size 2, 250Amps/48volt. Motor indeed a 205H50V3 We want to program the sevcon in limiting acceleration/torque to prevent dangerous situations, hence the 3 speeds, and 3 inputs...

    Titanium Fatbike - Bafang Ultra and Phaserunner

    Great info, thanks!! About the motor: I thought you ordered a 2500 watt but got a lighter one instead? The one in the link is the 1500W model, correct? Is the Phaserunner still needed then? Just saying once more: Great build, i love it! :)

    True, and might be so, but as you state yourself; even this one isn't really cheap as well.. Then, when you have a problem (like i do) and no support, it becomes really expensive....

    Wll, my version-1 BMS is still broke. Been trying to solve this from november 2013 on, but as good as no reply from eason unfortunately.... Greg is doing the best he can, but he needs Eason to send him parts, so he's stuck as well... I think its a bad thing that this goes on and on for 5 months...

    Hubmotor-on-fire question...

    Hello, A year ago, my electric scooter with 8Kw 13" hubmotor cought fire during the night while charging. To make a long story short: all is lost, exept the hubmotor. Now i found the courage to test it, and the windings seem to be o.k. The halls act really erratic, couldn't explain it... So, i...

    I think this is the time to let everyone know where i purchased this BMS. In the Netherlands there's a one-man show company **edited**, run by **Edited**, and he sold me the defective BMS. He literally told me to contact HIS supplier with these problems, as he didn't have any time for me ti...

    i will check the wiring again, but i done it many times, and each position i shift my testlead of my DMM, the voltage rises with approx. 3 volts, so... But i'll check it just to be absolutely sure.

    Gregor, I'm sure eason is not one of the thirteen-in-a-dozen chinese supplyers, but in a month time, there should be a spot of five minutes to send a reply, right? As for the BMS, i described above. From the first chip, voltages are not correct. The first and last cell of the firts chip are...

    Its a pitty... I still have a non-working version-1 BMS, and its been a month now since last contact with Eason. I find it very uncomfortable that i have a non working BMS for over 2 months now, and can't get to contact the vendor... What started as really enthoustiastic, is a bit of a bummer...

    Okay, I had the external current sensor the wrong way. In the drawing it is specified, but this seems to be the wrong direction. I took the time to reference the sensor, and put it the other way round on the cable. Now, when pulling current it gives negative energy, and when regenerating, it...

    foundingpower programmable bms

    Today i had my first drive with the BMS. I have to set the current and match it to a reference value, so its probably not exact yet. What bothers me, is this: I have fully charged the pack, charging current was 9 amps, so this could be quite correct. When full, i reset the pack value, so all...

    foundingpower programmable bms

    Can anyone tell me if it is also possible to put the current hall in the positive battery lead, instead of the negative? It naturally has to be wired the other direction, thats clear... Its a bit neater to wire in the positive, the way my setup is assembled.

    True, And to avoid such, i have a laptop thats solely used for such purposes, and i put it in a sleeve, together with this converter, and use it for all my programming.... I can try to re-install the driver on my regular laptop, and try programming it again with this converter. I have 2...
